  1. AirPrint uses multicast, most access points disable LAN to WLAN multicast and broadcast traffic by default as it can cause unwanted performance issues. This is generally due to length of time to send broadcast data to all WLAN devices. You should have an option somewhere to allow for multicast and broadcast traffic on the Wireless device, I'm unfortunately not familiar with the Rukus R700 but I would assume it has options to enable/disable this type of traffic.
  2. SSD's are consumables, people really need to digest and understand this. Eat their rated write endurance and it will be a door stop in no time. What bugs me is the article from BackBlaze is missing vital information, because i am assuming that they buy consumer grade SSD's and mechanical disks then throw them in to the fray expecting enterprise levels of endurance... not sure what else they would expect besides early failure rates. The article is incredibly misleading, an SSD will die within weeks if you obliterate it's potato flash write endurance in that time. What the article is missing What SSD models they were using and why What the budget per server was for the SSDs vs Mechanical drives What was the TBW at the point of failure (was it inside or outside manufacturer rated spec) Were SSDs behind a RAID/HBA controller with/without trim support and was the OS in use providing said support Are they utilising or reading the additional manufacturer specific S.M.A.R.T data provided As someone who has put over 50k SSD's in to environments from consumer to DC grade devices I find the whole thing misleading. I have seen numerous SSD's fail for all sorts of reasons but the biggest one by far is exceeding the manufacturer rated endurance, followed by Intel's 'DISABLE LOGICAL STATE' which still gives me nightmares to this day.
  3. Last time I saw something like this it was a fake Intel network card. Does the card have a yottamark validation sticker on it?
  4. Then it is very likely you have exceeded the write endurance of the drive. I have seen similar behaviour on SSD controllers in the past when a drive has expired all its flash write endurance.
  5. I would suggest checking the write endurance left on the drive, people seem to forget that SSD's are a consumable.
  6. In UK money, that would be around £60 which is about 66 Brexit currency
  7. When you flashed to IT mode, did you enter the original configuration for the controllers SAS address as part of the end process? I've seen this when the controllers SAS address isn't specified during the flashing process as a few guides miss it and its quite important as it provides the pathing for the pass-through to the disks (SAS Addresses) behind the controller. Some OS's don't require it to be present but Windows 2012 R2+ has always needed it. If you are unsure what the SAS address of the controller is, it is usually labelled on the device physically (assuming the label hasn't gone awol)
  8. AData SSD's are absolutely garbage, always have been and always will be. Did some testing with 8 su800 sata units as cheap consumer replacements on request of a purchasing manager to try and save on costs...... 3 units failed within weeks of the testing and verification phase they went straight in to the shredder, not even worth a warranty replacement. Buy shite, buy twice.
  9. As the old saying goes, buy shite buy twice.
  10. I'm with @Electronics Wizardy here, this is going to be a whole load of pain for very little gain unless you are solely doing this to expand your knowledge.
  11. Yea it can be virtualised but you are not going to get 10Gbit throughput from a virtualised network interface. You will have to use PCIe pass-through for the network interface(s) to reach that and place the interface in the dataplane
  12. Build a custom TNSR installation, its free now for home/non-commercial use. This is what the pfSense guys have been working on along side the pfSense project but uses a different way of handling traffic using VPP (Vector Packet Processing) and DPDK (Data Plane Development Kit) to minimise CPU cycles. These are developments on Linux to substantially improve per core packet processing capability. From around 1Gbit/s per core to around 10Gbit/s per core. https://www.tnsr.com/ https://www.tnsr.com/tnsr-vs-pfsense-software Can do 10G with ease, I would probably use Intel 10G, Mellanox Connect-X or SolarFlare cards in the installation. Can pick them up pretty cheap, I'm using a SolarFlare SFN5121 in my colo/test chassis running TNSR. Has no GUI, but does have a REST API and console access, can get it setup for normal internet usage pretty easily and may teach you something new.
  13. I'm assuming you have a dual socket motherboard with only 1 CPU populated? Only half of the memory banks are available if both sockets aren't populated. You will need to verify which are active in your manual but these are usually labelled A1,A2,A3 etc and the B1,B2,B3 etc slots are usually inactive as they require a 2nd CPU to be available. This is entirely dependant on your motherboard manufacturer of course so I would advise reviewing the manual to find out which dimm slots are inactive when using a single socket configuration. Also be aware that a number of PCI-Express Lanes will also be inactive in a single CPU configuration, so expect some of the PCIe slots to not function.
  14. You should really speak to network specialists about this and the ISPs you plan to be peering with to see what they do/don't support. I can suggest some additional reading for you; FastNetMon for detection based on custom parameters and upstream black holes to reduce network infrastructure impact BGPFlowSpec for more advanced upstream black hole rules to allow known good traffic types etc I would also suggest you to avoid trying to mitigate/filter attacks until you have 200Gbit/s+ of internet bandwidth capacity at a data centre. Considering you are asking this question, it is doubtful you have capacity to handle even a small attack. Write it in to your terms & conditions regarding what you would do in the event of an attack.
  15. Thats only part of the testing suite, thats the MSSQL testing which can be done on Linux but I certainly wouldn't want to use Linux for MSSQL at the moment.
  16. Not having a Windows license makes absolutely no different to features or performance on Windows Server OS Plus its only on that temporarily until it goes it to production, but its under testing currently anyway
  17. No complaints here from AMD's current offerings, 2.96Ghz on ALL cores for 2 fully loaded 7452 Rome CPUs .
  18. It wont see the traffic if the switch port being used has not been set to trunk and the vlans on the trunk port are allowed in the port configuration. This carries for all devices attached to the switch that require multiple (tagged) vlans per port.
  19. You can use DNSShell for powershell to update/modify/remove entries from the Windows DNS Service. https://archive.codeplex.com/?p=dnsshell You would need to use Powershell to determine the DyDNS record, then input using DNSShell The following would give you the dynamic IP address $ip as a string you could then use DNSShell to input; $ip = [System.Net.Dns]::GetHostAddresses("DYNAMICDNS.VALUE").IpAddressToString Then you can use the Set-DnsRecord function in DNSShell to modify the A record you have specified. Some examples are here; https://devblogs.microsoft.com/scripting/weekend-scripter-use-a-free-powershell-module-to-ease-dns-administration/
  20. You have the FTP port open to the public, it will be scanned, prodded and poked by all sorts of tools from all over the world. This is absolutely normal for any service that is open to the public, expect it to get probed and exploited should an exploit be available for the software version you are running. I wouldn't personally recommend using FTP as it's not very secure, but it also depends how much you care about the content being sent over it. I would also look in to locking down the firewall rules to per IP (if static) if dynamic per DNS value and use a service such as no-ip to run a dynamic DNS service on the dynamic IP provided by the ISPs.
  21. If memory serves it was able to run 1.38 volts to get 4.4 stable (silicon lottery?) I did have an excel document full of configuration settings used for each step of the way but I genuinely can't seem to locate it on any old hdd I had a lot of problems with memory compatibility, I ended up with some Kingston 800Mhz FB-DIMMS KTA-MP800K2 and had to lax off the timings to keep things stable due to the FSB bump. I also had a corsair active memory cooler on the top as the memory modules run HOT. The whole system ran hot and the power draw was colossal but it was a really fun system to build, I've always been an enthusiast for dual socket builds as I have always worked primarily with server hardware with dual and quad socket mainboards. Speaking of such, I do have a pair of X5492's which OC'd really well, I think they surpassed the QX9775's with similar voltage, I still have those knocking around in the basement if they are of any interest to you? Got a load of old hardware like that just sat in the basement doing nothing.
  22. Ah cool, genuinely confused at the start of the video then i was like.. pretty sure that's the box etc I sent over.. took me about 2 weeks to find the door hanger and all the docs for it so glad it saw some screen time. I'd love to see it overclocked and pushed to it's absolute limits, the SkullTrail was a bit of a difficult beast to overclock with as not much documentation existed around the board. I reset the BIOS before sending it and just verified it would boot with the QX9775's as it was running 4.4Ghz daily OC's back in the day on both chips and ran stable for everything outside of Intel's own CPU burn test (used to just lock up on dual socket due to some timing issue that would throw up 'hardware failure' on an Intel version of a blue screen of death). Maybe LN2 and push for some world records ;)? I believe the board and 9775's reached over 6Ghz at one point? If it makes good content for the community just detonate the board with LN2 and massive OC's ? The system was still pretty strong in gaming, I also have a EVGA SR-2 & dual x5690's but the board some soldering after it got dropped during a house move If I can get that working, may send it across too as that was the SkullTrail's replacement back in the day.
  23. Anyone able to clear something up? I sent Linus this exact board, 2x QX9775 CPU's and some FB-Dimms from the UK @LinusTech Is this my board being used here as the box looks like the one I sent across or is this @Overl0rd's equipment? Trying to figure out what has gone on here? Top job for Overlord if he did send another board, cpu's etc but I don't get where the board and equipment I sent has gone....? Anyone from Linus Media Group able to clarify whats going on here? Just wanna know if the stuff I sent was working etc
